PURPOSE:To enable the shifting between a no load operation and a loaded operation of the titled engine to be made only by the switching operation of a valve by a method wherein the compressor is evacuated or the air in the compressor is substituted with helium when air vaporized from liquid phase air is supplied so that the requiried driving power is applied on a generator to thereby increase the power generation output of the generator. CONSTITUTION:The liquid phase air 1 is stored in a storage vessel 3 from a pipe 2 and is introduced into the air turbine 13 through a liquid phase air vaporizer 6 and an air heater 9 via a pipe 2 and a pump 5 when the electric power demand reaches its peak so that the vaporized air expands adiabatically. Then the air sucked into the compressor 21 of the gas turbine 20 is introuced into a burner 22 after being compressed to about 12atm. and the resulatant combustion gas is introduced into the gas turbine 25 to generate a driving power so that the generator 24 is driven to generate electric power through a shaft 36 and at the same time, the compressor 21 is driven through a shaft 37. Further, after closing an inlet valve 27 of the compressor 21 to the full, the air in the compressor 21 and an air circulation passage is substituted with helium gas by opening a valve 50 provided in a pipe 49 leading to a helium gas vessel 51 whereby the compressor is operated in substantially a no-load operation condition. |
